Re: 1/10 Liebherr Excavator R 984 Litronic
Thank you, Ed. But I've to go a long way to the end, remember, this project started in September 2011. But I think it's going down the hill!
We come closer to the bucket but first I'll show up with the OilQuick120 quick coupler. Fortunately I was supported from the manufacterer with a drawing and some really good pictures. For this I had to made some really small double-acting cylinders. First tests with compressed air were successful.
Half of the parts were lasercut parts, the others were milled/ premachined by Michael. First I drilled the 1mm holes up to 1.3mm for tapping with 1.6mm (I'm proud to tap 48 holes without breaking that little sucker). Later there will be screwed covers whitch will hold the bolts in place.
The cylinders are simple brass tubes with the head soldered in place. Then I did some internal lathe work for the o-rings on the front and for the lockring on the backside. Really simple made.
